What I'm looking for

I'm open to remote, hybrid, and global relocation opportunities, and available for on-call and 24/7 production support.

At RingCentral India Pvt Ltd, I led the migration of 40+ mission-critical databases from on-premises data centers to AWS EC2 and RDS, cutting infrastructure costs by 30%. I also deployed GoldenGate 19c for near-real-time replication and improved batch job completion times by 35% through performance tuning.

At NextGen Healthcare India Pvt Ltd, I delivered 20+ Qlik Replicate CDC tasks across Oracle, AWS Redshift, and S3, reducing data latency from hours to under five minutes. I also administered Oracle databases and backups, and configured Active Data Guard.

At Collabera, for Intuit India Product Development Centre, I planned and executed zero-downtime migrations of 25+ databases from Oracle 11g to 19c using GoldenGate. I also implemented TDE across RAC and Data Guard environments and contributed to RAC and Active Data Guard build activities.

Earlier, at Oracle India Pvt Ltd and Accenture Services Pvt Ltd, I worked on Oracle monitoring, patching, migrations, backup and recovery, and Data Guard. I hold Oracle Database 12c Administrator, OCI Architect Associate, AWS Solutions Architect – Associate, and ITIL v2 Foundation certifications.
